Answer:
96.1 grams of percent yield
Answer:
Explanation:
We know we will need an equation with masses and molar masses, so let’s gather all the information in one place.
M_r: 16.04 32.00 44.01 18.02
CH₄ + 2O₂ → CO₂ + 2H₂O
m/g: 10.0 40.0
1. Moles of CH₄
2. Mass of CO₂
(i) Calculate the moles of CO₂
The molar ratio is (1 mol CO₂ /1 mol CH₄)
(ii) Calculate the mass of CO₂
3. Mass of H₂O
(i) Calculate the moles of H₂O
The molar ratio is (2 mol H₂O /1 mol CH₄)
(ii) Calculate the mass of H₂O
Answer is convalent . When electrons are shared, this is a convalent bond. Now if the electrons are transferred and not shared, this is an ionic bond. Ionic bonds are stronger than convalent bonds.
Answer:
In order to cancel the electrons,. the oxidation half reaction must be multiplied by 4 and the reduction half reaction must be multiplied by 3.
Explanation:
Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.
Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
The half cell reactions for the above reaction follows:
Oxidation half reaction:
Reduction half reaction:
Thus, in order to cancel the electrons,. the oxidation half reaction must be multiplied by 4 and the reduction half reaction must be multiplied by 3.
Thus,
4*Oxidation half reaction:
3*Reduction half reaction:
Overall reaction:-
Answer:
2.567
Explanation:
To change milliliters into liters you divide by 1000
So when you divide 2567 by 1000 you get 2.567
